It should be noted that, sizes and shapes in the drawings do not reflectthe true scale, and are merely intended to schematically illustrate thepresent disclosure. Furthermore, the same or similar reference numeralsthroughout represent the same or similar elements or elements having thesame or similar functions.

With such advantages as low energy consumption and self-illumination,the display panel of an organic light emitting diode (OLED) is one ofthe hot spots in the research field of display panels of flat panels.Since OLED is a current-driven light-emitting device, it needs aconstant current to control its light emitting. For general OLED displaypanels, a pixel circuit is adopted to generate a drive current to drivethe OLED to emit light. In some embodiments, the pixel circuit isgenerally provided with a transistor and a capacitor, and then a drivecurrent can be generated through mutual combination between thetransistor and the capacitor to drive the OLED to emit light.

To improve homogeneity of characteristics of the transistor in the pixelcircuit, as shown in FIG. 1A, a virtual pixel circuit 121 can be set inthe peripheral area BB surrounding the display area AA, tosimultaneously prepare the pixel circuit in the display area AA and thevirtual pixel circuit 121 in the peripheral area BB, so as to improvehomogeneity of the transistor in the display area AA.

In view of this, embodiments of the present disclosure provide a displaypanel, as shown in FIG. 1A, the first light emitting device 111 in thefirst display area aa1 is driven to emit light through the virtual pixelcircuit 121 in the peripheral area BB, so that the first display areaaa1 can achieve the light-emitting display effect, thereby not onlyenabling the whole display area AA to achieve the light-emitting displayeffect, but also improving the light transmittance in the first displayarea aa1.

In some embodiments, the present disclosure provides a display panel, asshown in FIG. 1A and FIG. 1B, the display panel can include:

-   -   a base substrate 100, including a display area AA and a        peripheral area BB surrounding the display area AA, the display        area AA includes a first display area aa1 and a second display        area aa2;    -   a plurality of pixel circuits, including a plurality of virtual        pixel circuits 121 and a plurality of drive pixel circuits 122,        the plurality of virtual pixel circuits 121 are arranged in the        peripheral area BB, and the plurality of drive pixel circuits        122 are arranged in the second display area aa2;    -   a plurality of light emitting devices, arranged on a side,        facing away from the base substrate 100, of the plurality of        pixel circuits, the plurality of light emitting devices include        a plurality of first light emitting devices 111 and a plurality        of second light emitting devices 112, the plurality of first        light emitting devices 111 are arranged in the first display        area aa1, and the plurality of second light emitting devices 112        are arranged in the second display area aa2;    -   at least one virtual pixel circuit 121 is electrically connected        with at least one of the first light emitting devices 111, and        at least one drive pixel circuit 122 is electrically connected        with at least one second light emitting device 112.

In some embodiments, through using the drive pixel circuit 122 in thesecond display area aa2 to drive the second light emitting device 112 inthe second display area aa2 to emit light, the second display area aa2can achieve a light-emitting display effect. And, through using thevirtual pixel circuit 121 in the peripheral area BB to drive the firstlight emitting device 111 in the first display area aa1 to emit light,the first display area aa1 can achieve a light-emitting display effect.Therefore, the whole display area AA can achieve a light-emittingdisplay effect. Since the first display area aa1 is provided with afirst light emitting device 111 and is not provided with a pixel circuitor metal traces (for example, a drive gate line 131 and a drive dataline 161), therefore, not only the first display area aa1 can achieve adisplay function, but also the first display area aa1 does not need tobe provided with pixel circuit and metal traces, so that lighttransmittance of the first display area aa1 is improved. In this way,when the display panel is applied to the display device, a front camera,a sensor, a receiver and other elements can be arranged below the firstdisplay area aa1 of the display panel, to achieve full screen design andimprove the screen-to-body ratio.

In some embodiments, the virtual pixel circuit 121 which drives thefirst light emitting device 111 to emit light can be the virtual pixelcircuit which is arranged in the peripheral area BB to improvehomogeneity of the characteristics of the transistor of the pixelcircuit in the display area. In this way, through reusing this part ofvirtual pixel circuit 121 in the peripheral area BB to drive the firstlight emitting device 111 in the first display area aa1 to emit light,the first display area aa1 can achieve a light-emitting display effect.Moreover, there is no need to set up additional virtual pixel circuitsin the peripheral area BB, thereby ensuring that the width of theperipheral area BB is small.

In some embodiments, the display panel can include: a plurality of pixelunits arranged in the first display area aa1 and the second display areaaa2 in an array. Each pixel unit includes a plurality of sub-pixels spx.Exemplarily, the pixel unit can include a red sub-pixel, a greensub-pixel and a blue sub-pixel, in this way, color display can beachieved through mixing red, green and blue. Or, a pixel unit can alsoinclude a red sub-pixel, a green sub-pixel, a blue sub-pixel and a whitesub-pixel, in this way, color display can be achieved through mixingred, green, blue and white. Of course, during practical applications,the light emitting color of the sub-pixel in the pixel unit can bedesigned and determined according to actual application environment,which is not defined herein.

In some embodiments, the pixel distribution density in the first displayarea aa1 can be less than the pixel distribution density in the seconddisplay area aa2, in this way, the light transmittance of the firstdisplay area aa1 can be further improved.

In some embodiments, a plurality of first light emitting devices 111 arearranged in the first display area aa1 in an array, and a plurality ofsecond light emitting devices 112 are arranged in the second displayarea aa2 in an array. For example, in the first display area aa1, asub-pixel can include a first light emitting device 111. In the seconddisplay area aa2, a sub-pixel can include a drive pixel circuit 122 anda second light emitting device 112, and the drive pixel circuit 122 andthe second light emitting device 112 in the same sub-pixel areelectrically connected with each other. And, a row of the first lightemitting devices 111 and a row of the second light emitting devices 112can be in the same row, and a column of the first light emitting devices111 and a column of the second light emitting devices 112 can be in thesame column. In this way, the first light emitting devices 111 in thefirst display area aa1 and the second light emitting devices 112 in thesecond display area aa2 can be set uniformly.
